Thanks for all your advice! It's great to have such support from a fantastic community!

I've read about rsync and various other "of the shelf packages" and various articles suggest that one doesn't get a proper copy of the files with this way of doing things? Like not all attributes are copied, some of the packages like chronosync do not copy resource forks properly..blah blah. SuperDuper is the only thing that copies the files completely. I don't understand the intricacies of the BSD file systems on Mac.

So my questions are
1. Does this matter when one is mirroring/updating directories with say pdf files. I'm not trying to do a full backup per sais.
2. Is chronosync one of these packages that don't copy all file attributes, I KNOW SuperDuper is the best for this but the interface is clumsy for what I want to do.
3. I know rsync doesn't copy everything but is it enough to do what I want?
